I recommend that you keep goldfish, which is simple and easy to keep, and it is not easy to die, but how much you keep depends on how big your fish tank is! If the tank is not big enough, if you raise more goldfish in summer or dog days, you may die of hypoxia! It doesn't matter if you have an aerator in your water tank!

You are suitable for raising:

1-2 black butterfly tail or dzi beads (out of the eye) and celestial eyes (avoiding villains). If you like black, black goldfish can only account for one-third to one-half of the total number of goldfish. Too much is bad for your fortune!

2-3 alternating gold plating or lanshou with white and red, (safe and smooth)

2-3 lion heads with gold or yellow and white or red and yellow, (lucky)

2-3 red hats or red tops (life is booming)

1-2 five-flower gold plating or eye gold (this kind of good-looking and auspicious)

You have never raised or fed goldfish before. If the tank is big, I suggest you choose grass goldfish from koi fish or goldfish.

You can mix them freely, and you can ask me if you don't understand!

The setting of the fish tank depends on whether you want to set it according to Feng Shui or your own preferences!

If you want to place it according to your own preferences, I suggest you put the fish tank by the window or by the balcony. It is best to have sunshine every day! It would be better to put a light on the fish tank in the living room!

If you decide the location according to the geomantic omen, I need you to provide your floor plan and the layout of the house, the size and shape of the fish tank, the variety, color and quantity of fish, all of which are very important! So I'll tell you where it is!

I hope my answer can help you!
